This guide will let you know where to study the Caretakers Footprints in Fortnite. Follow the simple steps in this given to study the footprints.
When you are on the beach, you will need to go to the petrol station to fill up your car tank. When you are on the way, you will see the pink craters on the side of the road, and these are the footprints you have to study. Interact with one of them, which will count as one footprint studied, and you can only do one at each location.
If you go to the Bony Burbs, you can find these footprints near the reboot van located in the middle of the street, and when you find it, you have to interact with it, and it will complete your quest.
